Based in Milton Keynes, Ceravision is a private UK company that is leading the world in the development and exploitation of High Efficiency Plasma (HEP) lighting technology.  HEP lighting, based on microwave-powered electrodeless discharges, can use a large range of light emitters unavailable to conventional discharge lighting systems.

Currently focused on UV grow-light solutions for horticulture, this plasma lighting lends itself to several other high-output applications including UV-C for air and water sterilisation.  In horticulture, HEP's  flexibility in providing tailored spectral distributions, long life, high efficiency and added-value is persuasive. 

The UV420 plasma grow-light delivers UV-B, UV-A and blue light, and is designed to work alongside other grow-lights to deliver the missing 280 to 550 nm wavelengths.  UV-B and UV-A influence plant physiology through particular receptors and components to enhance nutritional and medicial qualities.  In medicinal cannabis production for example, this UV grow-light enhances flowering and significantly boosts cannabinoid and terpene concentrations.
